Application filed March 3, 1916. Serial as. 81,967

To all whom it may concern:

Be it known that we, Hanan T. HnArs and WILLIAM luAcnaui\Y. citizens ofthe United States, rcsiding'at liewance. in the county of l'l'enry andState of Illinois, have invented new and useful Improvements in 1 ofwhich the following is a specification. V

This invention relates to inu'irorements in heating devices and hasparticular applica tion to a liquid fuel burning submersible heater. i

In carrying out the present invention. it is our purpose to provide. aheater of the class described which may be submerged in a tank of wateror other liquid to heat the same and wherein the supply of fuel to theburner may be regulated so as to accelerate or retard the heating of thewater or other liquid, and wherein the productsot' combusphere, all ofthe heat units being extracted from the products of combustion a thelatter pass to the atmosphere, thereby enabling the Water to be heatedin a comparatively short time and with a minimum cousump tion of fuel.

\Vith the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthin and falling within the scope of the claim.

In the accompanying drawings; Figurenl is a view in elevation of aheater constructed'in accordance with our present invention, the samebeing shown immersed in a tank of water; Fig. 2 is a vertical tionalviewv through the heater. Fig. 3 is a crosssectional view on the line 33of Fig. 2. Fig. 4 is a cross sectional view on the line l-l of Fig. 2. II

Referring now to the d 'awmg's il'l detail. 1 designates a rectangularcasing: adapted to he placed in a tank" containing water or other liquidto be heated and having the top wall thereof formed adjacent to the endwalls of th casing with openings and uprising from the top wallconcentrically of the openings 2 respectively are fines 3 of a heightsuliicicnt to project above the water line of the receptacle! in whichthe tank is arranged. Secured the upper ends of the lines 3 are hoods lspaced apart from the upper edges of the fines to form anair space.between the hoods and the fines.

Specification of Letters Eatent.

These hoods serve toprevent the entrance of rain, etc. to the flucs, butpermit the passage ofair through the fines. The can tral portion of thetop wall of the rectan gular casing 1 is concave-convex as at 5 andarranged beneath the concave-convex portion of the top wall of thecasing is a burner 6 and arrangedimmediately abovethe burner 6bctween'the latter and the portion o Is a perfo'ated grate 7 designed tobreak up the blaze from the burner, while Patented June 2?, 331%..

encircling the burner and depending from'fh the bottom edgeyof theconcaro-conrer; tion 5 is a shield 8 that acts to deflect the heatfronrthe burners; Arranged across the fiues 3, 3 respectively at thelower ends thereof are air dampers. 9 pivoted Within the respectivefiues forswinging movement and connected with chains 10 that extendupwardly in the fines and have the upper ends thereof trained over theupper edges of the Hues so that the chains may be operated to open andclose the dampers'so as to vary the quantity ofair passing through thelines.

The burner 6 is'of any suitable construction and is equipped with acontrolling valve 11 connected through the medium. of"

suitable gearing 12 with the lower end of a, vertical shaft 13ar'an'gedin one of the dues 3 and having the upper end thereof terminatingadjacent-to the upper end of the line so that the shaft may be rotatedto open and close the valve.

H designates a supply tank located in some suitable position andconnected by means of a pipe line 1:) with the burner 6,. the pipe lineextending down through one of the fines 3.

The concavo convex portion 5 of the to wall of the casing l ispreferably lined with asbestos 16 and is formed with vent holes fromwhich lead vent pipes 17 extending upwardly from the casing andterminating above the water line of the tank in which the heater isarranged. Y a

t ll

In )llK'lI-lCO the heater is laced in the tank containing the water orother liquid fines and the vent pipes the Water may circulate betweenthe same so as to expedite the heating of the water in the tank.

While We have herein shown and described the preferred form of ourinvention by Way of illustration, we wish it to be'understood that we donot limit or confine ourselves to the precise details of constructionherein described and delineated, as modification and variation may bemade Within the scope of the claim and without departing from the spiritof the invention.

We claim:

A heater adapted to be submerged in a tank of water or other fluid to beheated comprising a easing, air fines extending up Wardly from thecasing at the respective ends thereof and terminating above the wa terlineii the central portion of the topwall WARREN T. HEAPS. WILLIAMTHA-QKERAY.
